PLANING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 264,959, datedSeptember 26', 1882.

VApplication iled September 9, 1881. (No model.)

To all whom 'Lt may concern:

Beit known that We, LYMAN O. ORTON and LUCIEN ELBERRY, both citizensofthe United States, residing in the city and county of Philadelphia andState of Pennsylvania, have'inventedanew and useful Improvementin Wood-Planing Machines, which improvement is full y set forth in the followingspecification and accompanying drawings, in which- Figure l is a sideelevation of the planingmachine embodying our invention. Fig. 2 is atransverse vertical section thereof in line x fr,

1. Fig. 3 is a longitudinal vertical section of a portion thereofenlarged; Fig. 4 is a transverse vertical section in line yy, Fig. l.Fig. 5 is a horizontal section in linezz, Fig. l. Fig. 6 is a verticalsection in line w m, Fig. 4, the cutter-head being removed.

Similar letters of reference indicate corresponding parts in the-severalgnres.

Our invention relates toimprovements in machines for planing timber andboards; and it consists in grouping the cutting-cylinders in such mannerthat timber may be planed absolutely square.

It also consists in placing the cutting-cylinders for planing 'the lowerside of the vtimber or board in front of the other cutting-cylinders,for the purpose of producing a tinished side from which to work, or bywhich to gage the other sides.

It also consists of means for removing the lower cylinder and itsframe-or saddle for purposes of sharpening and adjust-ing the cutters'.

lt also consists of a novel method of vertically adjusting the lowercutting-cylinder.

1t also consists of means for raising and lowering the topfeeding-rollers by hand or power.

"It also consists of .a method of weighting the upper feeding-rollers.

It also consists of means for removing the side cutting-cylinders fromthe path of the board or adjusting the same for planing bevel or tapersurfaces, as will be hereinafter set forth.

Referring to the drawings, Arepresents the frame of the machine, to the.sides of which' are fitted vertically-moving bearings B, which carrythe upper feeding-rollers, C C. (Shown raised in Fig. l.)

| To each bearingB is pivoted a link, aa, which isipivoted to acrank-arm, b, fixed to the shaft o ot' a worm-wheel, D, said shaft beingmounted on the frame A.

Each wheelD engages with a worm, E,which is connected to a rotary shaft,F, which extends in the longitudinal direction of the machine, and hasits bearings on the sides of the frame A, it being noticed that theseveral worms for the worm-wheels arelocated on said shaft F.

Suspended from each shaft o is an arm, G, which is ot curvedor angularform, its upper end being adapted to be engaged bythe worm E on theshaft F, and the lower end bearing against a bridge, H, from Vwhichdepends a link, J, which is connected to the weighted lever K, thelatter being pivoted to the frame A.

It will be seen that the arms Gare in pairs, those of a pair facing eachother and the bridge H straddling them, whereby one weighted lever Krenders service for each arm G.

It will also be seen that the worms and worinwheels employed inconnection with the pair of arms are pitched in reverse order, as morereadily seen in Fig. 1.

'lo one end of the shaft F is connected a worm-wheel, d, with whichmeshes a worm, c, on a sl1al't-,f, whichlatter extends transversely, ismounted on the frame A, and carriesa crankhandle or crank-wheel, g, andloose and xed @rating the shaft F by hand or power.

The worms E are each fitted to the shaft F by a spline or feather-key,whereby, whilel they motions thereon.

Located on the shaft adjacent to each worm is a stop, E/consisting oftwo sleeves fitted to each other telescopically, and secured to theshaft by means of screws which permit adjustmentof the stop relativelyto the requirements of the worm.

1t will now be seen that when the board or timber is advanced to thefeed-rollers, and is engaged thereby, it raises said rollers,I which aremounted on the vertically moving or sliding bearings B, as has beenstated. The elevation of the bearings B raises thelinks aand crank-arm band rotates the shaft o, and consequently the worm-wheels D. Thesewheels pulleys l1., whereby provision is made for op rotate with saidshaft, they also have sliding IOO lIO

thus act as pinions and bear against the worms E as a rack, and impartsliding motions to said worms on the shaft F, so that they press againstthe upper ends of the arms G and lift the bridge H, whereby the weightedleversK are elevated. In this manner the weights of said levers areexerted on the sliding frames or bearings B and the feed-rollers areheld down firmly to their work. After the hoard or timber is run throughthe feed-rollers and bearings lower, and the parts assume their normalpositions.

When it is desired to raise the upper feedrollers by power the belts ofthe pulleys h, which belts lare operated from suitable parts of themachine, (see Fi g. 5,) are properly shifted, so that the shaftfisrotated; or said shaft may be operated by the handle or wheel g in orderto raise the feed-rollers by hand. The wormgearing e d operates theshaft F, whereby the worm-wheels D are rotated. The shafts c of saidwheels D turn the crank-arms b, which lift the links a, and therebyelevate the frames or bearin gs B. As the upper feed-rollers are mountedon said bearings it is evident that they are properly raised. When thetimber is inserted between the rollers the rotation of the shaft F isdiscontinued, and the upper rollers lower on the timber. This causes thedescent of the frames or bearings B, the rotation of the worm-wheels,the sliding movement of the worms, the operation of the arms G, and theconsequent action of the weighted levers on the, upper feed-rollers, ashas been before stated.

L represents the lower cutting-cylinder; M, the upper cutting-cylinder,both of which are mounted horizontally and transversely on the frame A,and N N two side cutters, which are mounted vertically on the frame A,the several cylinders having power applied to their mandrels or shaftsin any suitable manner.

It will be seen that the several cylinders are grouped for the purposeof planing timbers square or on four sides, and made to effect suchplaning absolutely square. Said cylinders are placed opposite to eachother as exactlyv as possible. Furthermore, the cutting-cylinder L, forplaning the lower sides ofthe timber or board, is in front of the otherthree ,cylind ers, thus producing a finished side for the timber orboard, which side, moving as the bed of the machine, gages the othersides, thus producing true work.

The bearings or frame L' of the cylinder L are connected to atransversely-sliding piece, P, said frame having vertical slots,vthroughwhich are passed bolts Q, which screw into the piece P, which is boltedto a frame, It, the latter also supporting the other cutting-cylinders,MN, the slide P being dovetailed to said frame R, and said frame R beingbolted to the frame A. When the bolts Q are loosened thecutting-cylinder L may be raised or lowered, or adjusted relatively tothe amount of' work i to be performed, after which the bolts aretightened and the parts retain their ad j usted positlons. In order toconveniently raise and lower the f'rame L' of said cutter-cylinder L,V

the under side of said frame is inclined, and to said side is fitted awedge, S, whose outer angular end, S", carries a threaded journaledbolt, S', to engage with a threaded opening in the frame P. By rotatingthe bolt there is, im-

vparted to the frame vL' a vertical movement which is slow and accurateand parallel or uniform on both sides.

1t will be seen that the wedge S is tongued, and the frame L' isgrooved, in the present ease of dovetailed form, whereby the wedge maybe inserted from the side of the machine, and lateral displacement ofthe wedge is prevented. The wedge, furthermore, extends entirely acrossthe frame L', the contiguous faces of the wedge and frame being a singleincline, thus employing but a single wedge-shaped bar for the adjustmentof the lower cuttingcylinder.

The slide P and frame lt are connected by bolts Q'. When the latter areunscrewed or withdrawn the slideP may be displaced from the frame R, andthe lower cutting-cylinder, L, thereby entirely removed for purposes ot'sharpening, adjusting, and repairing said cutters. By withdrawing thebolts Q" of the frame B al1 of the cutter-cylinders may be removed forsimilar purposes.

'lhe side cutting-cylinders, N, may be adj usted laterally or set at anangle for planing taper or bevel faces, as follows: Each bearing orframe of the mandrel or shaft of the cuttin gcylinders is pivoted, as atk, to a slide, T, which, having a segmental slot, m, is dovetailed tothe frame R to admit of transverse or lateral adjustment by theoperation of the screws T', which are rotated in the bearingframe N'.

When either of the cutters N is to be set at an incline, or to have itsangle of inclination changed, the set-screws a, which operate insegmental slots m, are slacked. The frame'of' said cutter is then turnedon its pivots k in either direction, as desired, and when the positionsought for isattained the screws a are tightened. Both cutters may beadjusted in this way into inclined posit-ions. When it is desired toadjust either of the cutters toward or from the other without incliningit or changing its angle of inclination the screws a are not disturbed,but the bearing-frame and connected parts of each'cutter-frame,including slide T, are moved as one by its screw T'.

By means of the adjustment of inclination above referred to the cuttersare adapted to plane bevelfaces of greater or less angle. Ethermethod ofadjustment allows them to be moved away from the path of the timber, soas not to obstruct the same. Furthermore, the pivots k and bolts orscrews a provide means for connecting the frame of each cutter N withthe respective slide T at different points, thus securely attaching saidframe and slide, and preventing motion or shifting ofthe former from itsadjusted position.
